application required MPG123 to play a continuous loop of every MP3

the -Z option which does this directly, but files are played in

This batch file presumes a Sabrent system environment variable set
from the sound device property details as described earlier.
Substitute the correct location of your MP3 files. Remove the -m
option if you want stereo.

This batch file can be initiated directly from a scheduled task
created to launch when windows starts (or other trigger). Each
version of Windows has its own idiosyncrasies starting a batch file
from a scheduled task, and I recommend a Google search if you have
difficulties. Ditto for having the batch file run in a minimized CMD
window, or no window at all. Consider flushing all console output
(stdout and stderr) when you invoke the batch file from a scheduled
task. For this batch file saved as PLAYEM.BAT- enter “PLAYEM >
nul 2>&1” on the command line<span style="font-variant: normal"><font color="#242729"><font face="Consolas, Menlo, Monaco, Lucida Console, Liberation Mono, DejaVu Sans Mono, Bitstream Vera Sans Mono, Courier New, monospace, sans-serif"><font size="2" style="font-size: 10pt"><span style="letter-spacing: normal"><span style="font-style: normal"><span style="font-weight: normal">.</span></span></span></font></font></font></span>
